Abstract
An annuloplasty prosthesis and delivery system for implanting the prosthesis adjacent an annulus of a heart valve having leaflets for adjusting the annulus to improve valve function includes a ring prosthesis made of shape memory material and having tissue attachment members which attach to the annulus in the atrium and commissural legs extending from the ring between the leaflets and secure against the underside of the valve in the ventricle. The prosthesis is carried via an orientation loop and attaches to the heart tissue such that when the prosthesis is manipulated and relaxed the annulus is adjusted to reduce or eliminate regurgitation.
Claims24
A system, comprising:
- an orientation loop connected to a terminal end of a first lumen and connected to a terminal end of a second lumen, at least a portion of the first lumen disposed within the second lumen;
- and
- a first guidehead connected to the orientation loop.
A system, comprising:
- an orientation loop connected to a terminal end of a first lumen and connected to a terminal end of a second lumen, at least a portion of the first lumen disposed within the second lumen;
- and
- a prosthesis holder system configured to slide along the orientation loop for placement of a prosthesis adjacent a heart valve.
A prosthesis delivery system for delivering a prosthesis adjacent an annulus of a heart valve of a heart, the system comprising:
- a catheter configured to be positioned within an atrium chamber of the heart;
- an orientation loop disposed within the catheter and configured to be expressed from the catheter and configured such that a portion of the orientation loop is deliverable through the heart valve to the ventricle such that a first segment of the loop is configured to be oriented at a first commissure of the valve and a second segment of the loop is configured to be oriented at a second commissure of the valve;
- and
- a prosthesis holder system configured to utilize the orientation loop for placement of a prosthesis adjacent the heart valve.
